Service Description: [Google Quota Control API](/service-control/overview)

Allows clients to allocate and release quota against a [managed service](https://cloud.google.com/service-management/reference/rpc/google.api/servicemanagement.v1#google.api.servicemanagement.v1.ManagedService).

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (QuotaControllerClient quotaControllerClient = QuotaControllerClient.create()) {
   AllocateQuotaRequest request =
       AllocateQuotaRequest.newBuilder()
           .setServiceName("serviceName-1928572192")
           .setAllocateOperation(QuotaOperation.newBuilder().build())
           .setServiceConfigId("serviceConfigId650537426")
           .build();
   AllocateQuotaResponse response = quotaControllerClient.allocateQuota(request);
 }
 

Note: close() needs to be called on the QuotaControllerClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Method	Description	Method Variants
AllocateQuota	Attempts to allocate quota for the specified consumer. It should be called before the operation is executed. This method requires the `servicemanagement.services.quota` permission on the specified service. For more information, see [Cloud IAM](https://cloud.google.com/iam). **NOTE:** The client **must** fail-open on server errors `INTERNAL`, `UNKNOWN`, `DEADLINE_EXCEEDED`, and `UNAVAILABLE`. To ensure system reliability, the server may inject these errors to prohibit any hard dependency on the quota functionality.	Request object method variants only take one parameter, a request object, which must be constructed before the call. allocateQuota(AllocateQuotaRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. allocateQuotaCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of QuotaControllerSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 QuotaControllerSettings quotaControllerSettings =
     QuotaControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 QuotaControllerClient quotaControllerClient =
     QuotaControllerClient.create(quotaControllerSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 QuotaControllerSettings quotaControllerSettings =
     QuotaControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 QuotaControllerClient quotaControllerClient =
     QuotaControllerClient.create(quotaControllerSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 QuotaControllerSettings quotaControllerSettings =
     QuotaControllerSettings.newHttpJsonBuilder().build();
 QuotaControllerClient quotaControllerClient =
     QuotaControllerClient.create(quotaControllerSettings);

Constructor Detail

QuotaControllerClient

protected QuotaControllerClient(QuotaControllerSettings settings)
                         throws IOException

Constructs an instance of QuotaControllerClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.

Throws:

IOException

QuotaControllerClient

protected QuotaControllerClient(QuotaControllerStub stub)

Method Detail

create

public static final QuotaControllerClient create()
                                          throws IOException

Constructs an instance of QuotaControllerClient with default settings.

Throws:

IOException

create

public static final QuotaControllerClient create(QuotaControllerSettings settings)
                                          throws IOException

Constructs an instance of QuotaControllerClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

Throws:

IOException

create

public static final QuotaControllerClient create(QuotaControllerStub stub)

Constructs an instance of QuotaControllerClient, using the given stub for making calls. This is for advanced usage - prefer using create(QuotaControllerSettings).

getSettings

public final QuotaControllerSettings getSettings()

getStub

public QuotaControllerStub getStub()

allocateQuota

public final AllocateQuotaResponse allocateQuota(AllocateQuotaRequest request)

Attempts to allocate quota for the specified consumer. It should be called before the operation is executed.

This method requires the `servicemanagement.services.quota` permission on the specified service. For more information, see [Cloud IAM](https://cloud.google.com/iam).

**NOTE:** The client **must** fail-open on server errors `INTERNAL`, `UNKNOWN`, `DEADLINE_EXCEEDED`, and `UNAVAILABLE`. To ensure system reliability, the server may inject these errors to prohibit any hard dependency on the quota functionality.

Sample code:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (QuotaControllerClient quotaControllerClient = QuotaControllerClient.create()) {
   AllocateQuotaRequest request =
       AllocateQuotaRequest.newBuilder()
           .setServiceName("serviceName-1928572192")
           .setAllocateOperation(QuotaOperation.newBuilder().build())
           .setServiceConfigId("serviceConfigId650537426")
           .build();
   AllocateQuotaResponse response = quotaControllerClient.allocateQuota(request);
 }
 

Parameters:

request - The request object containing all of the parameters for the API call.

Throws:

com.google.api.gax.rpc.ApiException - if the remote call fails

allocateQuotaCallable

public final com.google.api.gax.rpc.UnaryCallable<AllocateQuotaRequest,AllocateQuotaResponse> allocateQuotaCallable()

Attempts to allocate quota for the specified consumer. It should be called before the operation is executed.

This method requires the `servicemanagement.services.quota` permission on the specified service. For more information, see [Cloud IAM](https://cloud.google.com/iam).

**NOTE:** The client **must** fail-open on server errors `INTERNAL`, `UNKNOWN`, `DEADLINE_EXCEEDED`, and `UNAVAILABLE`. To ensure system reliability, the server may inject these errors to prohibit any hard dependency on the quota functionality.
